Title: Sliding gate type exhaust brake; excess pressure relieved through sprung sliding gate in main gate
Inventor: HARRIS V A
IPC: F02D9/06
Filed: 1986-06-06
Abstract: A slidable gate assembly is to be mounted on an exhaust brake having a housing (10) with aligned inlet and outlet apertures (13,14) to allow the passage of exhaust gas through the housing. The flow of exhaust gas is controlled by a slidable valve gate (15) forming part of the slidable gate assembly and having an exhaust gas relief passage (56) therethrough. The valve gate is mounted one end of the piston rod (21) and at that same end there is provided a closure device (60) for opening and closing the exhaust gas relief passage in the valve gate. A biasing force applied through the piston rod (21 preferably by a coil spring (61), biases the closure device (60) towards a closed condition of the exhaust gas relief passage. The piston rod (21) is movable relative to the valve gate (15) to open the exhaust gas relief passage (56) through the valve gate in dependance upon the force applied by the biasing spring (61). The closure device is forced to an open condition by the pressure of exhaust gas applied through the exhaust gas relief passage to the closure device. With this construction the biasing spring (61) can be located at a position remote from the body of the exhaust brake so as to be operable below the setting temperature of the spring.

Title: Omelette mix includes egg, a hydrocolloid and a salt solution
Inventor: MCMULLEN JAMES HENRY
IPC: A23L15/00
Filed: 1987-06-10
Abstract: An omelette mix is prepared from a liquid egg product, which may be, for example, whole egg, egg white, egg yolk, a de-chloresterized or artificial mix, or any combination of two or more of the foregoing, by adjusting its pH, preferably with citric acid, then adding to it a hydrocolloid, comprising an alginate, adding a multivalent metal salt of only low solubility in water, e.g. calcium sulphate dihydrate, in order to facilitate any required cross-linking of the hydrocolloid molecular chains, mixing thoroughly to form a homogeneous material, forming this material into any desired shape and freezing or chilling it to produce a stable intermediate material that can readily be quickly heated to give an omelette in form ready for consumption. In general sodium chloride will be introduced into the mix, conveniently with the hydrocolloid, in order to enhance the flavour of the omelette. A sequestrant is desirably added to control the release of the multivalent metal salt and thus regulate the speed of the cross-linking reaction.

Title: Apparatus for preparing blood or plasma component solutions of known concentration
Inventor: JORGENSEN GLENN A
IPC: G01N21/07
Filed: 1998-01-08
Abstract: The apparatus for separating a fibrin monomer from blood comprises; a container (110) with a reaction chamber defined by an outer wall for receiving plasma, a means for supplying the chamber with an agent for converting the fibrinogen content of the plasma into a non-cross-linked fibrin polymer; a device for centrifuging the plasma and the agent within the chamber to a degree sufficient for separating the non-cross-linked fibrin polymer from the plasma, depositing the polymer on the outer wall of the chamber and expelling the remaining plasma from the chamber; a means for supplying the chamber with a solvent for dissolving the non-cross-linked fibrin polymer, a measuring device (130) for measuring the thickness of the deposit of non-cross-linked fibrin polymer on the outer wall of the container (110); and a control unit (131) for controlling the addition of solvent in response to the amount of polymer. The apparatus may be used to determine the concentration of blood or plasma component in a solution by utilizing a comparison of intensities of a constant light transmission through the light transmissive wall. Polymer mass is determined by the formula: polymer mass = C In (R/F) where; C is a component coefficient (slope of a plot of polymer mass versus In (R/F); R is the light transmissive intensity through the wall alone; and F is the light transmissive intensity through the wall plus polymer. Concentration, Conc, is determined by the formula: Conc =    C In (R/F)               VB + C In (R/F) where; VB = the volume of buffer or solvent to be added.

Abstract: A multi-step process by which plant somatic embryos can be sown and germinated ex vitro using conventional seeding equipment, growing mixes, and plant propagation environments. The process most preferably comprises the steps of: placing a somatic embryo on or within a three- phase substrate, the phases comprising solid, liquid and gas phases, placing the substrate containing a somatic embryo into an environmentally-controlled plant-growing environment in which at least one environmental factor (i.e. moisture level within the three-phase substrate, atmospheric humidity, temperature, nutrients, ambient light intensity and diurnal photoperiod) may be controlled and manipulated, manipulating at least one of the environmental factors to enable and facilitate germination of the somatic embryo, and applying water and/or nutrient solutions at regular intervals, the intervals preferably ranging from 1 minute - 24 hours, to the surface of the substrate in the form of microdroplets, preferably for a period of time ranging between three to eight weeks, such that somatic embryo imbibition, germination, growth and development occur. The process can be practiced in non-sterile conditions with "naked" fresh and/or HRHT-treated and/or desiccated embryos, i.e., non-encapsulated or otherwise uncoated embryos, and does not require the use of aseptic techniques or sterilized media or equipment.
